Exxon knew earlier than almost anyone else about the dangers of climate change – but spent millions on funding climate change denial. An expose last month revealed that the oil giant knew about the effects of carbon dioxide on the climate as far back as 1977 – over ten years before most of the world had heard of the looming climate crisis. Yet, despite its own extraordinary research into the impacts of fossil fuels on the earth, the company has spent decades at the forefront of climate denial; lobbying to block federal and international action to curb emissions, and helping create a web of misinformation that continues to this day.
